. Specification of Letters Patent.

Patented Jan. 7, 1919.

7 Application filed October 10, 1917. Serial No. 195,793.

To all whom it may concern:

Be it known that I, JOHN M. DoLL, a citizen of the United States, a resident of Shreveport, in the parish of Caddo, State of Louisiana, have invented anew'and useful Improvement in Manifolds, of which the following is a specification.

This invention relates to manifolds and has particular reference to that class of manifolds employed in connection with internal combustion engines and serving both as a means of conveying gaseous fuel into the combustion chamber of the engine and transmitting the exploded gases therefrom to a distant and remote point.

An important object of the invention is to provide a device of the above mentioned character for utilizing the heat of the exhaust to heat the gaseous fuel in'its travel into the combustion chamber, thus rendering the fuel more highly explosive than Would otherwise be possible, thereby increasing the efficiency of the engine.

A further object of the invention is to provide a device of the above mentioned character which may be applied to the conventional designs of internal combustion engines without necessitating a change or altering of parts of same.

Other objects and advantages will be apparent during the course of the following description.

In the accompanying drawing, forming a part of this specification like numerals are employed to designate like parts throughout same.

Figure 1 is a side elevation of the device embodying my invention.

Fig. 2 is a central horizontal longitudinal sectional view of same, and

Fig. 3, is a central vertical longitudinal sectional view of Fig. 1; and

Fig. 1 is a central transverse sectional view of the same.

In the drawings, wherein for the purpose of illustration is shown a preferred form of my invention, the numeral 5 indicates a casing provided at one end thereof with a nipple 6, carrying a flange 7 which is adapted to receive thereupon a similar flange 8, which is carried by an exhaust pipe 9, the two flanges, 7 and 8, being secured together by means of bolts 10 or the like as shown.

Within the casing 5 there is disposed a pair of vertical walls 11 and 12 extending throughout the entire length of the interior of the casing 5 and forming a chamber 13 bounded by the walls of easing 5 and the walls 11 and 12. These walls may be either cast integral with the casing or secured therein as distinct and separate elements by any suitable means.

A partition designated by the numeral 14 is disposed between walls 11 and 12 at an appreciable distance from one end of the casing 5 as shown. This partition extends upwardly within the chamber 13 to an appreciable distance and is joined at its upper end with a bafiie 15 disposed horizontally within said chamber. A partition 16 is dis posed at the other'end of the chamber 13, which partition is identical with that indicated at 1 1 and has a baffle 17 secured at the upper end thereof, said baffle being identical with thatindicated by the numeral 15.

Substantially near thecent'er of the chamber 13 there is disposed a third bafile 18, ex tending horizontally within the chamber 13 immediately above the opening 19 provided within the casing 5, which opening connects the chamber 13 with the interior of pipe 20, secured to the casing 5 by means of bolts 21 as shown, the pipe 20 serving to direct fuel from a source of supply, not shown, into chamber 13.

The casing 5 is provided with a removable plate 22 which is provided with intake ports 23 and 24 and with a plurality of exhaust ports indicated by numerals 25. Around each of the intake ports and exhaust ports there is disposed a flange or offset 26. When the plate 22 is placed upon the casing 5 there is a chamber 27 formed between the wall 12 and the plate 22, as clearly shown in Fig. 1. Upon the other side of the casing 5 there is disposed a removable plate 28, forming a chamber 28 within the casing 5 and between the Wall 11 and said plate. These plates together with the manifold as a whole are held in place when applied to an internal combustion engine by means of bolts 29 passed through each of the plates and the channels or guides 30 of the tubes 31.

The chamber 27 is connected with the chamber 28 by means of pipes or tubes 32 which serve to direct exhaust gases from the chamber 27 to the chamber 28 as indicated by the arrows shown in Fig. 2. A pipe or tube 33 serves to direct gaseous fuel from the chamber 13 formed between the walls 11 and 12 into the intake port- 23, and a similar pipe or tube 33 serves to direct gaseous fuel from the chamber 13 into the intake port 2 1.

In use, the operation of my device is'as follows: Gaseous fuel is supplied to the manifold as a whole through the pipe 20 into chamber 13 whereupon it is deflected by the bafiie 18, passing around the same as shown by arrows of Fig. 3. The gaseous fuel after having been deflected by the baflie 18 passes over and around the bafiies 15 and 17 and enters the intake ports 23 and 24 whereupon it passes into the combustion chamber of an internal combustion engine. After the gas has been exploded within the combustion chamber it passes therefrom and into the chamber 27, through the exhaust ports 25 as indicated by arrows in Fig. 2.

Exploded gases upon entering the chamber 27, pass into chamber 28 through pipes or tubes 32, whereupon it moves longitudinally within the last mentioned chamber and passes into the exhaust pipe 9 and is carried to a distant or remote point as desired.

It is to be understood the various changes in the shape, size and arrangements of parts may be resorted to without departing from the spirit of my invention or the scope of the subjoined claims.

Having thus described my invention, what I claim as new and desire to secure and Copies of this patent may be obtained for five cents each, by addressing the protect by Letters Patent of the United States, is:

1. A device of the character described 2. A device of the character described comprising a casing, a pair of walls dis posed therein forming a chamber therebetween, a removable plate having intake and exhaust ports provided therein, said plate being adapted for attachment to one side of said casing to form a chamber between one of said walls and said plate, a second removable plate adapted for attachment to the other side of said casing to form a chamber between the other of said walls and second named plate, a plurality of pipes connecting the second and third mentioned chambers, and an exhaust pipe secured to said casing for conveying exhaust gases fromthe third named chamber.
